I would think that the goal of a GPC is "an ammunition that matches 7.62 mm NATO ballistics at 1,000 metres in a package that is 30% lighter. The 6.5 mm Grendel does this, but not as completely as we would like. Put a bit of extra power behind a slightly lighter projectile and you have a truly impressive round that is as lethal at 0 metres as it is at 1,000 metres. At least that is the theory." Thus it would work on the current M4/M16/L85 platform with either a barrel/bolt change or a new upper. But the majority of parts now in the rifle would not have to be changed out. Just a bit more powder so that it comes close to the power of the .260 Rem/6.5x55mm/6.5 BRM.
The basic Grendel cartridge is 6.5x38mm with a case dia of 10.6mm. This gives a magazine of 25 which is a good compromise between the 20 round 7.62 mags and the 30 round 5.56 mags.
I would hope that the specs include a G7 bullet rather than the G1 type. If manufacturers then produce high quality OTM match bullets (consumer market), the performance will be stellar for hunting and matches.
